BACKGROUND As many as 70% of smokers with acute myocardial infarction (AMI) continue to smoke after hospital discharge despite high rates of inpatient smoking cessation counseling. Supportive contact after discharge improves quit rates but is rarely used. METHODS Using data from a meta-analysis of randomized trials of smoking cessation interventions and other published sources, we developed a...
An important class of codes widely used in applications is the class of convolutional codes. Most of the literature of convolutional codes is devoted to convolutional codes over finite fields. The extension of the concept of convolutional codes from finite fields to finite rings have attracted much attention in recent years due to fact that they are the most appropriate codes for phase modulati...
We document that a recurring release of already publicly available macro economic information, in the form of the U.S. Leading Economic Index (LEI), has a significant impact on aggregate stock returns, volatility and volume. This is despite the fact that a) it is widely known that the index is based on previously published data, and b) the exact procedure used to construct the index is also pub...

SETTING The Nord-Trøndelag Health Study (HUNT), a large population-based health survey in Norway. PARTICIPANTS 5050 individuals aged 60-69 years old at baseline in HUNT2 (1995-1997) who also participated in HU...
BACKGROUND The purpose of this study was to conduct a worldwide survey investigating the methods, efficacy, and safety of catheter ablation (CA) of atrial fibrillation (AF). METHODS AND RESULTS A detailed questionnaire was sent to 777 centers worldwide. Data relevant to the study purpose were collected from 181 centers, of which 100 had ongoing programs on CA of AF between 1995 and 2002. The ...
AIM Neuroprotection trials for neonatal encephalopathy use moderate or severe disability as an outcome, with the Bayley Scales of Infant Development, Second Edition (Bayley-2) Index scores of <70 as part of the criteria. The Bayley Scales of Infant and Toddler, 3rd Development, Third Edition (Bayley-3) have superseded Bayley-2 and yield higher than expected scores in typically developing and hi...
اﻧﺪازهﮔﯿﺮی و ﺗﺤﻠﯿﻞ ﺷﺎﺧﺺﻫﺎی ﺑﻬﺮهوری آب در روش های مختلف آبیاری (سطحی و تحت فشار) ﺑﻪ ﻋﻠﺖ ﻣﺤﺪودﯾﺖ ﮐﻤﯽ و ﮐﯿﻔﯽ اﯾﻦ نهاده ارزﺷﻤﻨﺪ از ﺟﺎﯾﮕﺎه ﺧﺎﺻﯽ ﺑﺮﺧﻮردار اﺳﺖ. هدف از این پژوهش مقایسه بهرهوری آب و بهرهوری اقتصادی آن در سیستمهای آبیاری بارانی و سطحی است. در این راستا از اطلاعات و دادههای تفصیلی سیستمهای آبیاری و عملکرد محصولات تحت کشت این سیستمها در سال 1390 در دشت قزوین استفاده شده است.اطلاعات...
A low-dispersion Keck I spectrum of SN 1980K taken in August 1995 (t = 14.8 yr after explosion) and a November 1997 MDM spectrum (t = 17.0 yr) show broad 5500 km s emission lines of Hα, [O I] 6300,6364 Å, and [O II] 7319,7330 Å. Weaker but similarly broad lines detected include [Fe II] 7155 Å, [S II] 4068,4072 Å, and a blend of [Fe II] lines at 5050–5400 Å. The presence of strong [S II] 4068,40...
به منظور بررسی نقش کشت مخلوط ذرت / سویا بر کارایی استفاده از منابع و جلوگیری از رشد علفهای هرز ، آزمایشی در سال 1385 در مزرعة پژوهشی دانشکده کشاورزی دانشگاه تهران واقع در کرج به صورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی با 3 تکرار انجام شد. عوامل مورد بررسی عبارت بودند از: 5 نسبت اختلاط دو گونه گیاه زراعی ذرت (Zea mays) و سویا (Glycine max) شامل: 0 % سویا: 100 % ذرت (P1)، 25 % سویا: 75...
